Apurva Mehta commented on KAFKA-5269:
-------------------------------------
It turns out that the `UNKNOWN_TOPIC_OR_PARTITION` is returned from the request
handler in KafkaAPis for the AddPartitionsToTxn and the TxnOffsetCommitRequest
when the broker's metadata doesn't contain one or more partitions in the
request. This can happen for instance when the broker is bounced and has not
received the cluster metadata yet.
The correct fix is simple: the client should retry the request when receiving
this error.
> TransactionBounceTest occasionally fails due to partition errors
